This was one of the coolest things I have ever had the opportunity to do. We were treated to a night where the mantas were very active and were able to see 12+ of them, which our guides told us was much more than normal. The captain and crew were very helpful and straightforward about what to expect and how the mantas would behave.
Special shoutout to one of our guides, Joe, who was very knowledgeable about the mantas and answered a ton of my and my friends' questions during our time in the water.
